Partial Rotary Valve Electric Actuator in the selection, in addition to attention and valves and other components of the matching, but also consider the electric actuator control mode. Partial Rotary Valve Electric Actuator in the control mode, the common switch-type Partial Rotary Valve Electric Actuator and adjustable Partial Rotary Valve Electric Actuator two, the main difference is the valve switch control function is different.

1, switch type electric actuator

Switch type Partial Rotary Valve Electric Actuator are also known as open-loop control type Partial Rotary Valve Electric Actuator, which perform only two functions when the valve is operated, that is, the valve can only be fully open or fully closed. Switch type Partial Rotary Valve Electric Actuator can not control the amplitude of the valve switch, it can not be precise control of the media flow.

Switch type electric actuator structure has a split structure and integrated structure of two. Separate structure of the switch-type electric actuator must be equipped with a control unit to complete the control operation, it is not easy to install the system as a whole, and the investment cost is greater, the failure rate is higher, is not conducive to diagnosis and maintenance.

One type of electric actuator is the control unit and the combination of Partial Rotary Valve Electric Actuator as a whole structure, do not need to match the control unit to complete the operation of the valve. Integral Partial Rotary Valve Electric Actuator support remote control, as long as the electric actuator output control information, it can complete their own operational tasks.

2, adjustable electric actuator

Adjustable Partial Rotary Valve Electric Actuator, also known as closed-loop control type Partial Rotary Valve Electric Actuator, this actuator in addition to the valve switch control function, but also on the valve opening to do precise control, in order to achieve precise control of the flow of the media. Adjustable Partial Rotary Valve Electric Actuator in the form of work, divided into electric open-type Partial Rotary Valve Electric Actuator and electric type Partial Rotary Valve Electric Actuator.

Electric open-type Partial Rotary Valve Electric Actuator and electric-type Partial Rotary Valve Electric Actuator work control signal is different in the selection should determine the form of work of Partial Rotary Valve Electric Actuator, otherwise the control system is not suitable, and difficult to modify.

Adjustable type of electric actuator with loss of signal protection, when the actuator because of line failure or other reasons can not receive the signal, will control the valve itself to open the state, usually the valve fully open, fully closed or keep in place The

Electric actuator, also known as the valve electric device, it is in different industries in the field of title, in the industrial pipeline valve industry called the valve electric device, in the instrument industry called Partial Rotary Valve Electric Actuator, but now the industry has no clear distinction, This article will be referred to as the name of the electric actuator.

Valve in the industrial pipeline control is often used in the important equipment, electric valve with the development of industrial automation, because the power source is easy to obtain, and under normal circumstances without maintenance advantages, compared to pneumatic, hydraulic and other different driving methods Equipment usage is more common. In the industrial field electric valve must have a higher reliability and safety, when the valve can guarantee the performance and life of the case, the safety of electric valves and reliability depends on the electric actuator, so the performance of Partial Rotary Valve Electric Actuator, control level Is the overall performance of electric valve machine technology level. So in the selection of Partial Rotary Valve Electric Actuator in addition to the basic elements must be considered, the proposed technical requirements to make it possible to maximize the value of electric valve.

Many types of Partial Rotary Valve Electric Actuator, different types and functions of the Partial Rotary Valve Electric Actuator and valves can be called after the electric valve, but often in the design, selection process only focus on the parameters of the valve ignored or not clear the electric actuator Related requirements, so that not only make the electric valve to play the best performance, but also in the installation, commissioning, the use of the process will also bring unnecessary trouble, and even to the production of serious consequences.

This article will focus on the selection of Partial Rotary Valve Electric Actuator to explain the main points, and the current intelligent Partial Rotary Valve Electric Actuator related functions to do a brief introduction, it will be today and the future of industrial automation and control the development of the mainstream products.
